[ptx] hugin CVS build fails (case sensitive filenames)

[Bruno Postle]

I can't build hugin from CVS, make fails with this error:

  ../include/panoinc.h:75:28: common/vector3.h: No such file or directory
  ../include/panoinc.h:76:28: common/matrix3.h: No such file or directory
  ../include/panoinc.h:84:35: PT/Panotoolsinterface.h: No such file or directory

These files do exist, but with different capitalisation:

  ./src/include/common/Matrix3.h
  ./src/include/common/Vector3.h
  ./src/include/PT/PanoToolsInterface.h
